HANGER FOR TELEPHONE-TRANSMITTERS.

SPECIFICATION forming part of- Letters Patent N0.'752,184,' dated February 16, 1904.

Application filed May 8, 1902. $eria1No. 106,48. (No model.) i

To all whom it may concern.-

Be it known that I, MICHEAL SETTER, a citizen of the United States of America, and a resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Hangers for Telephone-Transmitters, of which the followingis a specification.

My invention relates to devices for supporting telephone-transmitters.

It relates more particularly to a form of hanger or like device by which an ordinary transmitter may be suspended by cords or flexible conductors in front of the operator.

Generally stated, the object of my invention is to provide a simple, inexpensive, and efficient hanger whereby a telephone operators transmitter may be suspended in the foregoing manner.

A special object is to provide a form of hanger which will not necessitate any change or alteration in applying it to a transmitter of the ordinary pattern.

Another object is to provide a hanger of such form that it may be constructed from a sheet-metal stamping.

It is also an object to provide certain details and features of improvement tending to increase the general eificiency and to render a device of this character more serviceable and satisfactory in use;

To the foregoing ends my invention contemplates a transmitter-hanger constructed, preferably, from a sheet-metal stamping and provided with end portions adapted to be readily attached to the front and back of the transmitter without necessitating any alterations or changes in the latter. Preferably it is provided with a ring-like or circular front portion adapted to encircle the transmitter-mouthpiece and also with a flattened rear portion adapted to be clamped against the back of the transmitter-casing. Thus formed or shaped so as to embrace the transmitter-casing the hanger can have its upper portion formed with a transverse bar or. attaching portion having its ends formed with openings for the attachment and passage of the cords or flexible conductors.

in place by the threaded mouthpiece.

The nature and advantages of my invention will, however, hereinafter more fully appear. In the accompanying drawings,- Figure 1 is a side elevation of a telephone-transmitter having a hanger involving the principles of my invention adjusted properly in place. Fig. 2 is a front elevation of the transmitter and hanger shown in Fig. 1. Fig. 3 is a rear elevation of the transmitter and hanger shown in Fig. '1. Fig. 4c is a view similar to Fig. 1, but showing the mouthpiece and the back of the transmitter and also showing the hanger in section. Fig. 5 is a view showing the manner of applying the hanger to the transmitter, the circular front portion of the hanger being shown in position to be bent down and clamped Fig. 6 is a perspective of the hanger shown in the preceding views. Fig. '7 is a detail sectional view of the means for connecting the rear portion of the hanger with the transmitter-casing. Figs. 8, 9, l0, and 11 illustrate the method of constructing the hanger from a sheet-metal stamping or blank.

As thus illustrated, the transmitter can be of any suitable form or construction, it being preferable, however, to have the front of the casing constructed with an annular boss a and to provide the mouthpiece a with a threaded portion (1?, adapted to be screwed into the said boss. The back of the transmitter can be constructed with a flat surface a As shown in Fig. 6, it will be seen that the hanger B preferably comprises a circular or ring-like forward portion 5 and also a flattened or disk-like rear portion 6. Both of theseportions are connected by the shank portions 6 and b with the upper transverse portion 5*. This portion 32* is preferably formed with rounded end portions 6, having the openings 1). With reference to the method of attaching the hanger to the transmitter, the portion 6 is preferably formed with three openings 6 5 and Z)". Thus formed it will be seen that the annular portion Z is adapted to encircle the mouthpiece of thetransmitter and who clamped against the boss at by the shoulder a. .Preferably the hanger is constructed so that it requires a slight bending of the metal in order to clamp the said annular portion in place. The first step, however, in securing the hanger to the transmitter would consist in fastening the portion 6 upon the flat rear surface a This may be accomplished by employing the small block of insution C andby inserting a screw 0 through the back of the transmitter and into this block. The terminals of the transmitter can consist of insulated screws 0, adapted to pass through the back of the transmitter and also through the openings Z2 and Z2 With this arrangement the block of insulation C will serve to clamp the portion 6 in place, and the portion 6 can, as stated, then be clamped into place by screwing in the threaded mouthpiece. When thus adjusted, the cords or flexible conductors D can be passed through the openings Z) in the hanger, as shown in the drawings, and the cord ends or terminals d can then be inserted in sockets in the insulating-block C. The electrical connection between the screws 0 and these circuit-terminals can be obtained by employing the binding-screws 0 and the sleeves 0 In this way it will be seen that the hanger is adapted for attachment to the transmitter without necessitating any changes or alterations in the latter. In other words, the transmitter, although of a form ordinarily employed in subscribers sets, can through the medium of my improved hanger be quickly adjusted into place on the cords or flexible conductors which usually hang in front of the telephone-switchboard operators. As stated, the character of the hanger permits the transmitter to be used in this manner without in any way altering or changing its construction. The hanger thus formed can be constructed in any suitable manner, but preferably is composed of a sheet-metal stamping.

Fig. 8 illustrates the first step in constructing the hanger, which consists in cutting out a sheet-metal blank of the form shown. This blank is then reduced to the form shown in Fig. '9, it being observed that the portions 1 and 2 of said blank have been apertured and reduced to the form shown in Fig. 6. It will also be seen that in Fig. 9 the flat portions 3 and 4 have been provided with openings encircled by pressed or raised surfaces. In addition to this the blank has been bent at right angles along the line 5 5 and then again at right angles along the line 6 6. In this way the said blank is reduced to the form shown in Figs. 9 and 10. The next step consists in folding the blank into the shape shown in Fig. 6. When thus folded, it will be seen that the rounded end portions 6 are composed of the two portions 3 3 and 4 4, which have been brought together in cross-section. In section each end portion now appears as shown in Fig. 11. The two shank portions 8 and 9 of the blank are then bent into the form 'shown in Fig. 6, so as to give the hanger the final or completed shape. The edges of the pressed or rounded end. portions 3 3 and 4 4 of the blank after thus being brought together can now be soldered together and when thus united provide the hanger with a rigid transverse up-.

per portion having openings at each end adapted for the attachment of the cords or flexible conductors. Thus the hanger can be economically constructed from a sheet-metal blank or stamping involving but a single piece of metal. It'will be readily understood, however, as previously stated, that the hanger can be constructed in any other suitable or desired manner.

I claim as my invention- 1. A hanger for telephone transmitters, constructed from a single piece of sheet metal bent or folded into the proper shape and provided with openings for the attachment of the hanger to the front and rear portions of a transmitter.

2. A hanger for telephone-transmitters consisting of a circular front portion adapted to encircle the transmitter-mouthpiece, a flattened rear portion adapted for attachment to the back of the transmitter, a transverse upper portion provided at each end with openings for the attachment of the cords or flexible conductors, and shank portions for connecting the said front and rear portions with the said transverse portion.

3. The combination of a transmitter having a removable threaded mouthpiece and a flattened back portion, and a hanger having a ring-like portion adapted to be clamped in place by said mouthpiece, and having also a flattened portion adapted to be clamped in place upon the said back portion of the transmitter.

4. The combination of a transmitter having a removable mouthpiece, a hanger having a front portion clamped in place by said mouthpiece, and having also a rear portion secured to the back of the transmitter, and flexible conductors passed through openings in a trans: verse upper portion of said hanger and connected with the terminals of saidtransmitter.

5. A sheet-metal hanger having front and rear portions adapted for attachment to the front and rear portions of a telephone-transmitter.

6. Ahanger for telephone-transmitters consisting of a single piece of sheet metal folded into proper form and provided with a portion adapted to encircle the mouthpiece of the transmitter, and also with a flat portion adapted to be secured flatwise to the back of the transmitter.
